DIMM Installation Rules
At least one DIMM must be configured in slots supported by CPU 1.
Optimal memory performance can be achieved if the processors in a server are configured
with the same number of DIMMs and the DIMMs are evenly distributed among the memory
channels. Unbalanced configuration reduces memory performance and is not recommended.
In unbalanced DIMM configuration, DIMMs are not evenly configured for memory channels
and (or) processors.
l
If a processor is configured with 3, 5, 7, 9, 10, 11, 12, 13, 14 or 15 DIMMs, the DIMMs
are not evenly configured for memory channels.
l
If the processors in a server are configured with different number of DIMMs, the
DIMMs are not evenly configured for processors.
